The embodiments of the present application relate to the field of communications technology, and in particular to a method, device, electronic device, and readable storage medium for handling redirection failures.

When the cell network load is too large, in order to distribute the cell network load, the cell sends a blind redirect message to some electronic devices connected to this cell, and the electronic devices access other cells after receiving this blind redirect message.

In the related technology, after receiving a blind redirect message, the electronic device selects and accesses a new cell based on the history record of radio resource control (RRC). If the electronic device cannot locate in the newly accessed cell due to some reason (e.g., the frequency point power of the newly accessed cell is low), the electronic device re-accesses the original cell.

However, if the original cell still has an excessively large network load, the original cell will again send a blind redirect message to the electronic device, causing the electronic device to fail the redirect and be unable to connect to the network.

The purpose of the embodiments of the present application is to provide a method, device, electronic device, and readable storage medium for handling a redirection failure that can solve the problem of being unable to connect to a network when an electronic device fails in a blind redirection.

The following clearly and completely describes the technical solutions in the embodiments of this application, in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only some of the embodiments of this application, and not all of the embodiments. All other embodiments obtained based on the embodiments of this application without the need for creative efforts by those skilled in the art are within the scope of protection of this application.

The terms "first," "second," etc. in the specification and claims of this application are intended to distinguish between similar objects and are not intended to describe a particular order or sequence. It is to be understood that data used in this manner are interchangeable where appropriate, such that the embodiments of this application may be performed in an order other than that shown or described herein, and that the objects distinguished by "first," "second," etc. are generally of the same type and do not limit the number of objects, e.g., the first object may be one or more. Note that "and/or" in the specification and claims represents at least one of the objects connected, and the character "/" generally represents an "or" relationship between the related objects.

The method for handling redirection failure according to an embodiment of the present application can be used in scenarios where an electronic device performs a redirection after receiving a blind redirection message.

In the related technology, the cell in which the electronic device is located sends a blind redirect message to the electronic device because the network load is too large. After the electronic device receives the blind redirect message, if the newly accessed cell does not support the location of the electronic device, the electronic device re-accesses the original cell. At this time, if the original cell network load is still large, the electronic device receives the blind redirect message again, and according to the preset rule, the cell to which the electronic device is redirected within a short time remains unchanged, so the electronic device may switch between the two cells multiple times, which causes the electronic device to be unable to locate in the cell for a long time, and further causes the electronic device to experience network disconnection.

In the technical solution according to the embodiment of the present application, when an electronic device receives a preset number of blind redirection messages within a preset time, it indicates that a situation in which the electronic device has continuously failed to redirect has occurred. At this time, in order to prevent the electronic device from disconnecting from the network, the electronic device actively searches for nearby cells and selects and accesses the cell with the highest access priority, thereby improving the reliability of the electronic device when redirecting and avoiding a situation in which network disconnection occurs.

Below, we will explain in detail how to handle a redirect failure according to an embodiment of the present application through specific examples and application scenarios, with reference to the drawings.

As shown in FIG. 1, an embodiment of the present application provides a method for handling a redirect failure, which may include steps 201 and 202 as follows:

In step 201, if a blind redirect message is received a preset number of times within a preset time period, the redirect failure processing device acquires target information for N first cells.

Here, the N first cells are N cells that the first electronic device can search, and the target information is used to determine the access priority of each of the N first cells, where N is greater than or equal to 1.

For example, if the cell network load in which the first electronic device is located is too large and load balancing is required, a blind redirect message may be sent to the first electronic device, and the first electronic device will be redirected to another cell after receiving this blind redirect message.

For example, when the first electronic device receives a blind redirect message a preset number of times within a preset time, this indicates that the first electronic device has continuously failed in blind redirection, and at this time, the redirection failure processing device obtains target information of the N first cells, and determines the access priority of each of the N first cells based on the target information of the N first cells. That is, the blind redirect message received by the first electronic device a preset number of times within a preset time is a necessary condition for triggering the redirection failure processing device to execute the redirection failure processing method according to the embodiment of the present application.

Specifically, this blind redirection message is a blind redirection message sent by the original cell of the first electronic device. This blind redirection message is a radio resource control connection release (RRC Connection Release) message carrying blind redirection information.

As can be seen, if the first electronic device successfully accesses another cell after receiving a blind redirect message, it will no longer receive the blind redirect message sent by the original cell.

Exemplarily, the redirection failure processing device searches for cell signals within a surrounding range after the first electronic device has continuously failed to redirect, and establishes a frequency point library based on the frequency points of cells that satisfy the S criteria. And performs priority sorting on the frequency points in the frequency point library.

It should be noted that a cell that satisfies the above S criteria is a cell with a received power Srxlev>0 dB in the cell search and a signal quality Squal>0 dB received in the cell search.

In step 202, the redirection failure processing device accesses the target cell.

Here, the target cell is the cell with the highest access priority among the N first cells. The access priority of the N first cells is determined based on the access success rate of each of the N first cells in the blind redirection process.

For example, in order to prevent the first electronic device from failing to redirect due to the redirection failure processing device accessing the first electronic device again after the first electronic device has continuously failed to redirect, the access priority of each of the N first cells is determined based on the access success rate of each of the first cells in the blind redirection process.

Exemplarily, the access success rate of the first cell is the access success rate of the first cell within a first preset time before the redirection failure processing device acquires the target information of the N first cells.

In this way, when the first electronic device receives a preset number of blind redirection messages within a preset time period, it acquires target information for the N first cells and accesses the target cell with the highest access priority among the N first cells. When the electronic device fails to blind redirect, the electronic device actively intervenes and selects and accesses one reliable cell, improving the reliability of the electronic device's redirection and preventing a situation in which the network is disconnected due to the electronic device being unable to stay in a cell for a long period of time.

Optionally, in an embodiment of the present application, after the electronic device has experienced successive redirection failures, the electronic device must determine that the cell accessed during the redirection failure is an abnormal cell in order to avoid re-accessing the cell.

Exemplarily, prior to step 201 above, a method for handling a redirect failure according to an embodiment of the present application may include step 203.

In step 203, if the first electronic device receives a blind redirect message a preset number of times within a preset time period, the redirect failure processing device determines the second cell as an abnormal cell.

Here, the second cell is one of the N first cells that has the highest access priority and to which access has failed before the number of blind redirect messages received within a preset time period reaches a preset number.

For example, when the second cell is a blind redirect of the first electronic device, after accessing the cell with the highest priority according to the first preset rule and rearranging the access priorities of the N first cells according to the second preset rule, the second cell is not the cell with the highest access priority. Specifically, the second cell is the cell with the lowest access priority among the N first cells.

For example, after the redirect failure processing device determines the second cell as an abnormal cell, the first electronic device or other electronic devices may be prevented from accessing the abnormal cell by the following two methods.

Method 1
Optionally, in an embodiment of the present application, after the redirection failure processing device determines the second cell as an abnormal cell, the redirection failure processing device may prevent the first electronic device from accessing this cell again by lowering the access priority of the abnormal cell.

Exemplarily, after step 201 above, a method for handling a redirect failure according to an embodiment of the present application may include step 204.

In step 204, the redirection failure processing device updates the access priority of the second cell in the N first cells from the first priority to the second priority.

Here, the second priority is lower than the first priority.

Exemplarily, after determining that the second cell is an abnormal cell, the redirection failure processing device may lower the access priority of the second cell to the cell with the lowest access priority of the N first cells. When the redirection failure processing device accesses a new cell, it avoids accessing the second cell.

In this way, the redirection failure processing device determines a cell to which the electronic device has repeatedly failed to redirect as an abnormal cell, and prevents the electronic device from accessing this cell again by lowering the access priority of this cell.

Method 2
Optionally, in an embodiment of the present application, after the redirection failure processing device determines the second cell as an abnormal cell, the redirection failure processing device may share the abnormality information of the abnormal cell with other electronic devices by transmitting the abnormality information of the abnormal cell to a server, thereby preventing further access by other electronic devices to the abnormal cell.

Exemplarily, after step 204 above, a method for handling a redirect failure according to an embodiment of the present application may include step 205.

In step 205, the redirect failure processing device sends a first message to the server.

Here, the first message includes first abnormality information of the second cell, and this first message is used by the server to share the first abnormality information of the second cell with the second electronic device.

For example, the second electronic device is an electronic device that can receive the first abnormality information transmitted by the server, and the second electronic device may include the first electronic device.

For example, the first anomaly information may include at least one of the time when the blind redirection anomaly occurred, the signal strength of the cell when the blind redirection anomaly occurred, and the signal quality of the cell when the blind redirection anomaly occurred.

For example, after the first electronic device has consecutively failed redirections, the redirection failure processing device transmits the tracking area identity code (TAI), global cell identity document (ID), time information, signal strength (i.e., reference signal receiving power (RSRP)), and signal quality (RSRQ) of the second cell to the server.

For example, an abnormality probability threshold is set in the server, and after the server receives the abnormality information of the abnormal cell, if the abnormality information exceeds the abnormality probability threshold, the server transmits the abnormality information of the abnormal cell to another electronic device, for example, the first electronic device. In this way, after receiving the abnormality information of the cell, the first electronic device sets the abnormal cell to the end of the cell list that satisfies the S criterion in the frequency sweep result, and when receiving a system message of another normal cell, sets the reselection priority of the abnormal cell to the lowest priority in the list.

For example, the electronic devices that share the abnormality information of the abnormal cell may be electronic devices in the same tracking area (TA). When the first electronic device sends a first message to the server, the first message further includes a tracking area identity (TAI) of the tracking area in which the first electronic device is located.

In this way, after the redirection failure processing device sends a first message carrying abnormality information of the abnormal cell to the server, the server may share this abnormality information with other electronic devices to prevent the other electronic devices from accessing this cell.

More optionally, in an embodiment of the present application, the redirect failure processing device may further receive cell anomaly information shared by other electronic devices, thereby preventing the first electronic device from accessing the anomaly cell.

For example, the above step 201 may include the following steps 201a and 201b.

In step 201a, the redirect failure processing device receives the second message sent by the server.

Here, the second message includes second abnormality information of each of the M first cells among the N first cells, where M≦N and M≧1.

In step 201b, the redirection failure processing device determines the access priority of each of the N first cells based on the second abnormality information of each of the M first cells and the system information of each of the N first cells.

Here, the M first cells are cells that the electronic device failed to access in the blind redirection process. The second anomaly information includes at least one of the time period when the blind redirection anomaly occurred, the signal strength range of the cell when the blind redirection anomaly occurred, and the signal quality range of the cell when the blind redirection anomaly occurred. The second anomaly information is obtained based on the first anomaly information.

For example, the electronic device may be an electronic device including a first electronic device. That is, the first electronic device and other electronic devices may share cell anomaly information with the server.

For example, after receiving first abnormality information of an abnormal cell transmitted by an electronic device, the server generates second abnormality information based on the first abnormality information, and when the first electronic device considers the cell corresponding to the second abnormality information as a cell to be accessed, the server transmits the second abnormality information to the first electronic device.

It should be noted that the system information of the first cell is information obtained when the electronic device performs measurements on the cell, and includes 12 system information blocks (SIBs), where the embodiment of the present application mainly uses SIB3 and SIB5.

In this way, the redirect failure processing device can further prevent electronic devices from accessing a cell in which an anomaly exists by receiving cell anomaly information shared by other electronic devices.

Optionally, in an embodiment of the present application, when consecutive blind redirection attempts fail, the redirection failure processing device can not only autonomously determine the cell to access, but also pass the right of choice to the user, allowing the user to select the cell to access.

Exemplarily, the target cell may be a first cell among the N first cells that the first electronic device accesses based on a user selection. Here, the target information further includes status information.

Illustratively, prior to step 202 above, a method for handling a redirect failure according to an embodiment of the present application may include step 206.

In step 206, the redirect failure processing device displays the N identifiers and status information corresponding to each identifier.

Here, one identifier indicates one of the N first cells. The status information is used to indicate the network quality of the first cell.

For example, the status information may include at least one of signal strength, signal quality, and the number of connection interruptions.

For example, after the processing device of the redirection failure displays the target interface, the above step 202 may include the following steps 202a1 and 202a2.

In step 202a1, the redirection failure processing device receives a user selection input for a target identifier among the N identifiers.

Exemplarily, the selection input may be a user's touch input on the target identifier, or a voice command input by the user, or a specific gesture input by the user, and may be specifically determined based on actual usage demands, and is not limited to the embodiments of the present invention. Exemplarily, the touch input may be a user's drag input on a first identifier, which is used to adjust the display position of the target identifier among the N identifiers, and further adjust the access priority of the target identifier among the N identifiers.

In step 202a2, the redirect failure processing device responds to the selection input by accessing the first cell indicated by the target identifier.

Illustratively, an embodiment of the present application further provides a setting interface, in which a first option and a second option are displayed, and if a user input for the first option is received, after the above step 201, the redirection failure processing device displays a target interface. If a user input for the second option is received, after the above step 201, the redirection failure processing device directly accesses the target cell. Here, the first option is a manual processing option, and the second option is an automatic processing option. And, after the user selects the manual processing option, if the redirection failure processing device does not receive any user input within a second preset time after the redirection failure processing device displays the target interface, the redirection failure processing device directly accesses the target cell.

Illustratively, after the redirection failure processing device displays the target interface, the redirection failure processing device displays the N first identifiers in a first order according to the access priorities of the first cells indicated by the N first identifiers. After the redirection failure processing device receives a user drag input on the target identifiers, the redirection failure processing device may further, in response to the drag input, rearrange the access priorities of the first cells indicated by the N first identifiers displayed on the target interface based on a second order of the N first identifiers after the target identifiers are updated. The redirection failure processing device may access the target cells according to the access priorities of the N first cells corresponding to the second order.

For example, the manual selection interface (i.e., the target interface) shown in FIG. 2 displays the identifiers (identifier 21, identifier 22, and identifier 23) of three cells (cell A, cell B, and cell C) searched by the electronic device, and a comparison diagram of the specific values of the signal strength, signal quality, connection interruption count, and recommendation index of the three cells. The access priority of the three cells is cell A>cell B>cell C. The user may click on any one of the three identifiers to allow the electronic device to access the cell corresponding to this identifier. At the same time, the user may further adjust the access priority of the three cells by dragging the three identifiers.

It should be noted that the manual access method according to the embodiment of the present application may be used as a debug mode. For example, after an abnormality occurs in a cell and is repaired by a technician, the technician can use the manual access method to select the cell with the access abnormality and test whether it has recovered normally.

In this manner, the redirection failure processing device may further present status information of accessible cells to the user and access a new cell based on the user's selection.

The method for handling redirection failure according to the embodiment of the present application is such that when the electronic device receives a blind redirection message a preset number of times within a preset time, the electronic device acquires target information of N first cells and accesses the target cell with the highest access priority among the N first cells. When the electronic device fails to blind redirect, the electronic device actively intervenes and selects one reliable cell to access. Here, based on cell abnormality information shared by other electronic devices, the priority of a cell having an abnormality among the N first cells may be lowered to prevent the electronic device from accessing the cell having an abnormality. This improves the reliability of the electronic device when redirecting and prevents a situation in which the network is disconnected due to the electronic device being unable to stay in a cell for a long time.

It should be noted that the execution body of the method for handling redirection failure according to the embodiment of the present application may be a redirection failure processing device, or may be a control module for executing the method for handling redirection failure in the redirection failure processing device. In the embodiment of the present application, the redirection failure processing device according to the embodiment of the present application will be described by taking as an example that the redirection failure processing device executes the method for handling redirection failure.

It should be noted that in the embodiments of the present application, the methods for handling redirection failures shown in the drawings of each of the above methods are illustratively described as examples in conjunction with one of the drawings in the embodiments of the present application. When specifically implemented, the methods for handling redirection failures shown in the drawings of each of the above methods may be implemented in conjunction with any other attached drawings that can be linked as shown in the above embodiments, and will not be described further here.

In order to avoid repetition, no further description will be given here.

It should be noted that the electronic devices in the embodiments of this application include the mobile and non-mobile electronic devices described above.

Figure 4 is a schematic diagram of the hardware structure of an electronic device that realizes each embodiment of this application.

The electronic device 100 includes components such as, but not limited to, a radio frequency unit 101, a network module 102, an audio output unit 103, an input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, and a processor 110.

As can be understood by those skilled in the art, the electronic device 100 may further include a power source (e.g., a battery) for powering each component, and the power source may be logically connected to the processor 110 by a power management system, so that the power management system can realize functions such as charge/discharge management and power consumption management. The electronic device structure shown in FIG. 4 does not constitute a limitation on the electronic device, and the electronic device may include more or less components than the number of components shown, or a combination of some components, or a different arrangement of components, and will not be further described here.

Here, the radio frequency unit 101 is used to obtain target information of N first cells when the first electronic device receives a predetermined number of blind redirection messages within a predetermined time, the N first cells being N cells that the first electronic device can search, the target information is used to determine an access priority of each first cell in the N first cells, N≧1, and the network module 102 is used to access the target cell, where the target cell is a cell with the highest access priority among the N first cells, and the access priority of the N first cells is determined based on the access success rate of each first cell in the N first cells in the blind redirection process.

In this way, when the first electronic device receives a preset number of blind redirection messages within a preset time period, it acquires target information for the N first cells and accesses the target cell with the highest access priority among the N first cells. When the electronic device fails to blind redirect, the electronic device actively intervenes and selects and accesses one reliable cell, improving the reliability of the electronic device's redirection and preventing a situation in which the network is disconnected due to the electronic device being unable to stay in a cell for a long period of time.

Optionally, the processor 110 is used to determine the second cell as an abnormal cell if the first electronic device receives a predetermined number of blind redirect messages within a predetermined time period, where the second cell is one of the N first cells that has the highest access priority and has failed to be accessed before the predetermined number of blind redirect messages are received within the predetermined time period.

Optionally, the radio frequency unit 101 is used to send a first message to the server, the first message including first anomaly information of the second cell, and the first message is used by the server to share the first anomaly information of the second cell to the second electronic device, where the first anomaly information includes at least one of a time when the blind redirection anomaly occurred, a signal strength of the cell when the blind redirection anomaly occurred, and a signal quality of the cell when the blind redirection anomaly occurred.

In this way, after the redirect failure processing device sends a first message carrying abnormality information of the abnormal cell to the server, the server may share this abnormality information with other electronic devices to prevent the other electronic devices from accessing this cell.

Optionally, the radio frequency unit 101 is used to receive a second message sent by the server, the second message including second abnormality information of each of the M first cells in the N first cells, where M≦N and M≧1, and the processor 110 is further used to determine the access priority of each of the N first cells based on the second abnormality information of each of the M first cells received by the radio frequency unit 101 and the system information of each of the N first cells, where the M first cells are cells that the electronic device fails to access in the blind redirection process, and the second abnormality information includes at least one of the time period when the blind redirection abnormality occurred, the signal strength range of the cell when the blind redirection abnormality occurred, and the signal quality range of the cell when the blind redirection abnormality occurred.

In this way, the redirect failure processing device can further prevent electronic devices from accessing a cell in which an anomaly exists by receiving cell anomaly information shared by other electronic devices.

Optionally, the processor 110 is used to update the access priority of the N first cells of the second cell from a first priority to a second priority, where the second priority is lower than the first priority.

In this way, the redirection failure processing device determines a cell to which the electronic device has repeatedly failed to redirect as an abnormal cell, and prevents the electronic device from accessing this cell again by lowering the access priority of this cell.

Optionally, the display unit 106 and the user input unit 107 are further included, the target cell being a first cell among the N first cells that the first electronic device has accessed based on a user selection, the display unit 106 is used to display the N identifiers and status information corresponding to each identifier, one identifier indicating one first cell among the N first cells, and the status information is used to indicate the network quality of the first cell, the user input unit 107 is used to receive a user selection input for a target identifier among the N identifiers displayed on the display unit 106, and the network module 102 is specifically used to respond to the selection input received by the user input unit 107 and access the first cell indicated by the target identifier.

In this manner, the redirection failure processing device may further present status information of accessible cells to the user and access a new cell based on the user's selection.

In an embodiment of the present application, when the electronic device receives a blind redirect message a preset number of times within a preset time, the electronic device obtains target information of N first cells, and accesses the target cell with the highest access priority among the N first cells. When the electronic device fails to blind redirect, the electronic device actively intervenes and selects and accesses one reliable cell. Here, based on cell abnormality information shared by other electronic devices, the priority of a cell having an abnormality among the N first cells may be lowered to prevent the electronic device from accessing the cell having an abnormality. This improves the reliability of the electronic device when redirecting, and prevents a situation in which the network is disconnected due to the electronic device being unable to stay in a cell for a long time.
